* TheAbridgedSeries: ''[[http://whatdoesgodneedwithastarship.com/ A Rope of Robots]]'' is a text based one. As expected, it somehow manages to turn a very serious narrative into a side-splitting mockery.* CowboyBebopAtHisComputer: Ramsus' second Omnigear, Amphysvena, is mistakenly assumed to be Vendetta aligned to a second Anima Relic. According to [[WordOfGod the Perfect Works]], however, its actually Krelian's Omnigear -- Ramsus pilots it because Krelian has no more use for it.* ExecutiveMeddling: Disc 2 is pretty much Executive Meddling: The Game. According to Takahashi, they had only two years to finish the project and the new staff members and transition to 3D caused delays in the schedule. Ultimately, it was either end at Disk One or make Disk Two mostly narration to tell the whole story. See [[http://kotaku.com/the-real-story-behind-xenogears-unfinished-disc-2-1796151112 here]] for further details.* {{Expy}}: Elly has an uncanny resemblance to Elle from VideoGame/{{Terranigma}}, both in name and appearance** Rico is a dead ringer for [[Franchise/StreetFighter Blanka]]. No one is quite sure why. ** Emeralda is a green-haired orphan [[spoiler:sort of]] child that grows up within the game. Just like [[VideoGame/FinalFantasyIV Rydia]].** "I am [[strike:[[Franchise/StarWars Darth Vader]]]] [[strike:[[Anime/MobileFighterGGundam Master Asia]]]] [[strike:[[SpellMyNameWithAnS Graf]]]] Grahf, the seeker of power. Doth thou desire the power?"** Krelian shares his name (in Japanese, they're even spelled the same) and a few personality traits [[spoiler:but not appearance]] with [[Literature/ChildhoodsEnd Karellen]].** The relationship between Lacan and Krelian is similar to another well-known Squaresoft duo, [[VideoGame/FinalFantasyVII Cloud and Sephiroth]]. Likewise, the secondary villains (Deus/Mother) are basically identical to VII's secondary villain, Jenova (although Miyang had a bit more agency than Jenova did).* MemeticMutation: "Remember, kids...Chu-Chu died for your sins!"** "Did you just see my MAD SKILLZ?"* NamesTheSame: Chu-Chu shares her name with an animal friend from ''VideoGame/KirbysDreamLand3''.** Wiseman shares his name with two different villians: one in ''[[VideoGame/BatenKaitos Baten Kaitos Origins]]'', and another in ''VideoGame/NightsIntoDreams''.* UrbanLegendOfZelda: ** A few of them, the two most prominant are that you can somehow use Elly/Sophia's [=OmniGear=] El Regerus outside of the one scripted battle it appears in, and that you can recruit Ramsus as a playable character after [[spoiler:Elly merges with Deus]].*** These two originate from translated production notes in the ''Perfect Works'' books, outlining plans for El Regerus, Ramsus, and even Margie to be fully playable characters, only to have them get cut down to NPC status thanks to time and funding shortfalls.** Hilariously, you really can get the El-Regrs (Elly's Omnigear) by entering the final floor of the last dungeon and then going back out, but since its pilot is no longer in your party, it is useless. It's also playable in the Kislev battling minigame, but who enjoys grinding that?** For extra fun, it's possible to [[VideoGame/GameShark hack]] El Regerus into the game before Elly takes off, but it doesn't have a model for the overworld, causing a game crash.** There seems to be a rumor of a planned Xenogears OVA that takes place during the Zeboim era. So far, there's no evidence that such a thing was even planned.* WhatCouldHaveBeen:** Imagine Xenogears with a fully fleshed-out disc 2. For that matter, imagine Xenogears and VideoGame/{{Xenosaga}} as parts of a massive six-game epic.** Margie was originally going to be playable, hence the sketch in ''Perfect Works'' where she has [[TrenchCoatWarfare an entire arsenal hidden in her cloak]]. Better-known is the fact that Omnigear versions of Siebzehn and Crescens were designed but never implemented in the game.** There is a rough sketch of El Seibzehn, Maria's MidSeasonUpgrade, in ''Perfect Works''.** Kahran was originally planned as a SixthRanger, but this got canned when the budget ran out.** The intro for the game was meant to be longer, consisting of an animated opening credits (similar like anime openings) featuring the song "Stars of Tears" and the intro movie, but was cut. WordofGod said it would make the opening very long. (the combined length of the two would be roughly ten minutes, so yeah.)** The game was originally pitched as ''VideoGame/FinalFantasyVII'', but was eventually made its own thing because the story was considered too dark for a main ''Final Fantasy'' title.* WorkingTitle: ''Xenogears'' was originally called ''-Project Noah-'', but this was changed during development for unknown reasons. Presumably it's because Creator/SquareEnix didn't want the already controversial religious symbolism to extend to the title.----
